As an outsider, I've been following Go for a while, and given the lack of common high productive language features such as Generics and optional function arguments with default values, to me, it seems like right now Go is much better than C, and in some dimensions better than Java and in others worse. If it just adds a few things, and then when you account for portability and speed, it could be better than the dynamic languages that people often compare it to.
